Answer:
134.1 ft²
Step-by-step explanation:
<u>Fine the area of the square first, then subtract the area of the circle to find the area of the shaded part.</u>
The area of the square
= 25²
= 625 ft²
The radius of the circle
= 25 ÷ 2
= 12.5 ft
The area of the circle
= π × 12.5²
= 490.87385...
= 490.9 ft² (rounded up to the nearest tenth)
The area of the shaded part
= 625 - 490.9
= <u>134.1 ft²</u>
Answer:
∠1 = 47
∠2 = 63
∠3 = 70
∠4 = 70
Step-by-step explanation:
∠2 and 63 are alternate interior angles. Alternate interior angles are equal.
∠2 = 63
∠3 and 110 are linear pair angles. Sum of linear pair angles is 180.
∠3 + 110 = 180
∠3 = 180 - 110
∠3 = 70
GDEF is a parallelogram, so ∠DGF = ∠DEF
That is,
∠3 = ∠4
∠4 = 70
∠1, ∠2 and ∠3 are interior angles in a triangle.
Sum of interior angles in a triangle is 180,
∠1 + ∠2 + ∠3 = 180
∠1 + 63 + 70 = 180
∠1 + 133 = 180
∠1 = 180 - 133
∠1 = 47
The y intercept is -4 and the 2/3x is the slope
You just have you go a little bit over the number 5 on a number line
